I have a very weird problem.

I have 3 different code bases that I am working on each are their own window.

Suddenly one of the stopped working and keeps giving me the error as you can see. The other windows works fine not matter what llm i use.

Anyone experience that?

Hey, I can’t see that request ID on our end, which suggests a networking issue.

Can you confirm you are not using a VPN or corporate proxy, and if you are still having issues, try to disable HTTP/2 with this guide for better compatibility:
